Bludit version 3.16.2 contains a stored cross-site scripting (XSS) vulnerability in the post content functionality. The application performs client-side sanitation of content input but does not enforce equivalent sanitation on the server side. An authenticated user can inject arbitrary JavaScript into the content field of a post, which is stored and later rendered to other users without proper output encoding. When viewed, the injected script executes in the context of the victim’s browser, allowing session hijacking, credential theft, content manipulation, or other actions within the user’s privileges.
Bludit versions before 3.13.1 contain an authenticated file download vulnerability in the Backup Plugin that allows logged-in users to access arbitrary files. Attackers can exploit the plugin's download functionality by manipulating file path parameters to read sensitive system files through directory traversal.
A security vulnerability has been identified in Bludit, allowing authenticated attackers to execute arbitrary code through the Image API. This vulnerability arises from improper handling of file uploads, enabling malicious actors to upload and execute PHP files.
Bludit prior to 3.9.1 allows a non-privileged user to change the password of any account, including admin. This occurs because of bl-kernel/admin/controllers/user-password.php Insecure Direct Object Reference (a modified username POST parameter).
